Do you think they actually believe that it converges for all values of x, or do you think there's confusion around the meaning of the word 'valid'?

Absolutely all British ex-pats in Spain speak Spanish to at least A level standard, right?

The person who did win the Nobel Peace Prize will be delighted. I wish I were joking.

You can tell the best recipes in our cookbooks because they are the ones that are covered in greasy marks and traces of food. And, also notes about how they work better for us with certain tweaks.

Find the exact value of the green area.

The graphs of y = a/x³ and y = a - x³ are in red. They share a mutual tangent point in the first quadrant. The area enclosed by the x-axis and the two curves, with no upper limit, is shaded green.

No worries if you don't get round to it 😀 Hope the cold gets better soon.

I don’t suppose anyone has a scheme of work for AQA Level 2 Further Maths they would be willing to share with me? #MathsToday

I'm not sure I would only count calculations as steps...I think many students find identifying angles correctly to be the difficult bit

Maybe, but Susan is in the company of other people who also experienced it and are telling her it's real. I think TLTWATW is a great children's book, however you read it. You can be a Christian or not, you can understand the allegory or not, it's a cracking story. All that TLB has is the allegory.

I think it's a problem with allegorical writing. My interpretation of what you are saying is that the loss of faith equivalent is not implausible, but that does not stop what happens in the story being implausible in the story. The allegory is more important to Lewis than writing a good story.

I do recreational Maths a lot in my free time but I've never been to MathsJam, so I wouldn't necessarily attach too much weight on MathsJam attendance. A lot of Maths teachers are happy to chat about all things mathematical on social media.

It just couldn't be further from my experience. (I've only ever taught A level, nearly all in sixth form colleges, so maybe there's a difference between those and schools?)

Susan Whitehouse @susanwhitehouse.bsky.social · 3d

Really? Definitely not my experience...a lot of Maths teachers I know spend a lot of free time doing Maths puzzles of one sort and another

Shame on Labour for conflating anti genocide protests with anti Jewish sentiment -disgraceful

at the maths challenge club i run we have just finished senior maths challenge prep. Next stop is ritangle, but is there anything right now that year 7s or 8s or 9s could be getting on with?

There is one exam board that includes the Hessian matrix for determining the nature of stationary points of surfaces, but not eigenvalues/eigenvectors/diagonalization, and I struggle to know what to do to justify that beyond showing examples.

Susan Whitehouse @susanwhitehouse.bsky.social · 3d

Yes, I agree with you. You can also go a bit more formal for the case where f(a) and g(a) are both 0 by using Maclaurin expansions or a slightly fuzzy limits argument. I think that some teachers aren't very confident with the content at this level, and don't do anything like this.

I've come across a few things in the optional pure A level Further Maths modules, for example l'Hopital's rule, that the students generally just use as tools at this level without rigorous proof.
